Answer:

The correct answer will be option-B.

Step-by-step explanation:

A hypothesis is a proposed idea or statement which is formed after studying the earlier work related to the same issue. The hypothesis is therefore known as the educated guess and not just a prediction.

The hypothesis is more specific than a prediction as it explains the question to a limited extent. A good hypothesis is proposed in such a way that it should be testable through experiments and could explain the scientific question.  

Thus, Option-B is the correct answer.

Indicate a general rule for the nth term of the sequence a1 = 2 and r = √3.
pantera1 [17]

It is given in the question that,

a_{1} = 2, r = \sqrt 3

Since we have the value of r given, so we have to use the formula to find the nth term of the geometric progression, which is

a_{n} = a(r)^{n-1}

Substituting the values of a and r, we will get

a_{n} = 2( \sqrt 3)^{n-1}

So the correct option is the third option .

What are the solutions of the system 7x + 3y=-3 and y= -2*?
mafiozo [28]

Answer:

opt 4

Step-by-step explanation:

when x=0, 0+3y= -3, so y=-1    (0,-1) is solution

         when x=3 , 21+3y=-3,  3y= -3-21= -24

                                                    y= -8                  (3,-8) is also solution

Malachi bought a new fishing rod. The regular price of the fishing rod was $125.99. He bought it on sale with a 15% discount. Sa
Volgvan

If the discount is 15 percent, he still pays (100-15) or 85%

125.99 * 85%

125.99 * .85 = 107.09  is the price he pays for the rod

107.09 * .03 =3.21 is the sales tax

107.09+3.21=110.30 is the price of the rod with the discount and the tax

Use the model to solve for x. <br> A) no solution <br> B) x = 1 <br> C) x = -1 <br> D) x = 10/4
andreev551 [17]

Answer:

x = -1

Step-by-step explanation:

The equation is -2x + 3 = 2x +7

Group the terms together. Don't forget to change the sign

-2x -2x = 7-3

-4x = 4

Divide both sides by 4

-x = 1

Flip it over

x = -1
